한국어 어휘의 의미를 파악하기 위하여 어휘의 의미 중의성을 해결하는 것은 중요한 일이다. 본 논문에서는 한국어 다의어 기반의 어휘 의미망과 용언의 논항정보 등의 관계가 포함된 어휘지도(UWordMap)를 사용하여 용언의 의미 중의성 해소에 대한 연구를 진행한다. 기존의 의미 중의성 해소 연구와 같은 동형이의어 단위가 아닌 다의어 단위의 용언 의미 중의성 해소 시스템을 개발하였다. 실험결과 실험말뭉치로 품사 태그 부착 말뭉치를 사용했을 때 동형이의어 단위 정확률은 96.44%였고, 다의어 단위 정확률은 67.65%였다. 실험말뭉치로 동형이의어 태그 부착 말뭉치를 사용했을 때 다의어 단위 정확률은 77.22%로 전자의 실험보다 약 10%의 높은 정확률을 보였다.

It is our main aim in this study to discriminate the conceptual relationship between homographic descriptors. The roles of qualifier and the problems of the recent usage of qualifier such as Hangul, Hanja and foreign languages, which is based largely on the dictionaries, subject heading lists and thesauri, re analyzed within the framework of the our test thesaurus developed as a macro-the-saurus. Finally, we proposed some new ideas must be integrated into the Hangul qualifier in order to make it generally applicable within the field of dictionary, and the method of representing, selection principles and priority of Hangul qualifiers.

컴퓨터를 이용하여 명사와 용언의 의미를 자동으로 분별하는 것은 기계번역이나 검색 등의 기술에서 아주 중요한 기반 기술이다. 최근에 동형이의어 분별에 대한 연구 결과로 약 96%의 정확률을 보이는 시스템이 개발되었으나, 다의어 분별에 대한 연구는 아직 초기 단계로 일부 어휘만을 한정하여 연구되고 있다. 본 논문에서는 어휘지도를 이용하여 다의어를 분별하는 방법을 연구하였고, 어휘지도에 등록된 모든 일반 명사와 용언을 대상으로 실험하였다. 제안된 알고리즘은 문장에서 나타나는 명사와 용언의 관계를 어휘지도에서 찾고, 그 정보를 기반으로 다의어를 분별하였다. 아직은 그 정확률이 실용적인 수준이라고 볼 수는 없지만, 전체 다의어를 대상으로 실험하였고, 그 실험 결과를 분석함으로써 앞으로의 다의어 분별 연구 방향에 도움될 것으로 판단된다.

The purpose of this paper is to identify the workings of intonation realized in the endings through the spoken language. To achieve this objective, this paper has analyzed 300 minutes of spontaneous speech by women from Seoul and discussed the meanings of modality and their relationship with intonation. Intonation functions significantly in polysemous modal endings in epistemic and act modality. Epistemic modality is usually expressed through indirect and soft intonations such as L:, M: and LH, whereas act modality is expressed through direct and strong intonations such as H, HL and LHL. Intonation appears to be related to the Certainty degree of information, rather than classification of modality, Lengthening relate to indirectness, H with uncertainty, L with statements or affirmation, and HL and LHL relates to assertive attitude. This paper is significant as it has overcome the abstractness of existing modality studies and has engaged in objective and comprehensive analysis with actual spontaneous speech data.

The main stream of consumption about the products is tend to transfer from low price value with mass production, to the second value of products, such as pleasure, familiarity, humor, and metaphor. This second value is closely connected to a redundancy which are also related to modern science as well as product design. These terms such as matrials, identity, and gravitation, disappeared gradually, and these are substituted with an uncertainty principle, a fortuity, a contradictory concept, entropy etc. In sum this study focuses on the tendency of intelligency issue the recent design trends. This result shows that The 4th Column Thinking and Formation System which is related to an expansion and diversity of design intellectual ideas.

중간언어 (interlingua, IL) 구축을 지향하는 시각에서 단어의 다의성 (polysemy) 문제를 각종 워드넷의 기술 방식과 용례를 대비하여 논의하고, 센스(어의) 번호를 부착한 세계 워드넷 (Would Wordnet) 데이터베이스를 구상하고, 이 연장 선상에서 (Pustejvsky 식) 생성 어휘 부와 TMR(텍스트의미표상)이론을 가미한 제약기반 통합문법(CUG)으로 IL구축에 다리를 놓고, 이로부터 개별언어 기술로 변환한다.

기존의 멀티미디어 자료들을 직접 분석하여 메타데이터를 부여하던 기존 연구들은 멀티미디어 파일에 부여된 키워드에 해당하는 온톨로지가 존재하지 않는 경우 해당 멀티미디어 파일에 대한 직접 검색을 실시하지 않거나, 잘못된 의미가 부여된 키워드에 의하여 검색 결과의 정확성과 재현율이 떨어지는 문제점을 가지고 있었다. 본 논문에서 제안한 SASM은 키워드에 부여된 다의성과 동의성의 개념을 이용하여 WordNet을 이용하여 확장한 후, 확장된 키워드들을 이용하여 온톨로지가 구축되어 있지 않더라도 해당 이미지에 대한 직접 분석을 실시할 수 있으며, 키워드에 대한 동의성과 다의성을 이용한 확장된 키워드들을 이용함으로써 검색 결과의 재현율과 정확성의 성능을 향상시켰다.

Latent Semantic Analysis (LSA Landauer ＆ Dumais, 1997) is a technique to represent the meanings of words using co-occurrence information of words appearing in he same context, which is usually a sentence or a document. In LSA, a word is represented as a point in multidimensional space where each axis represents a context, and a word's meaning is determined by its frequency in each context. The space is reduced by singular value decomposition (SVD). The present study elaborates upon LSA for use of representation of ambiguous words. The proposed LSA applies rotation of axes in the document space which makes possible to interpret the meaning of un. A simulation study was conducted to illustrate the performance of LSA in representation of ambiguous words. In the simulation, first, the texts which contain an ambiguous word were extracted and LSA with rotation was performed. By comparing loading matrix, we categorized the texts according to meanings. The first meaning of an ambiguous wold was represented by LSA with the matrix excluding the vectors for the other meaning. The other meanings were also represented in the same way. The simulation showed that this way of representation of an ambiguous word can identify the meanings of the word. This result suggest that LSA with axis rotation can be applied to representation of ambiguous words. We discussed that the use of rotation makes it possible to represent multiple meanings of ambiguous words, and this technique can be applied in the area of web searching.

In recent years, word embedding has been a popular field of natural language processing research and a skip-gram has become one successful word embedding method. It assigns a word embedding vector to each word using contexts, which provides an effective way to analyze text data. However, due to the limitation of vector space model, primary word embedding methods assume that every word only have a single meaning. As one faces multi-sense words, that is, words with more than one meaning, in reality, Neelakantan (2014) proposed a multi-sense skip-gram (MSSG) to find embedding vectors corresponding to the each senses of a multi-sense word using a clustering method. In this paper, we propose a modified method of the MSSG to improve statistical accuracy. Moreover, we propose a data-adaptive choice of the number of clusters, that is, the number of meanings for a multi-sense word. Some numerical evidence is given by conducting real data-based simulations.

This paper is the outcome of attempting to approach for reading the Analects of Confucius through the polysemy of Chinese character and indecidability of articles. For this purpose at first, I explained which this Chinese character can be applied for 'philosophy language'. In the 16th century Matteo Ricci had tried to find out the possibility of ideographic script as standing for a universal language. On the other hand, Hegel and Heidegger strictly insisted on the Chinese character is inappropriate for expressing the logic thought of the human being. The reason was as next; firstly, this character had not the preposition and articles, and secondly the only one word could not indicates the bisemy including the meaning of opposition, lastly this language system expresses and communicates only with the change of word order without inflection. But With some scholar like Cassirer, Saussure and Derrida we can confirm the possibility which will discover the Chinese character for using the logic and reasoning language of from different view. Because in the language system of this Chinese character the connection of words in contexts is more important other than meaning as the individual word, in comparison to the language of the West. The Chinese character hides the original meaning until being what kind of event and thing relationship watch inside with different letters. So to speak, the Chinese character is called as 'language of indecidability'. For these points, even though The Chinese character lacks of preposition, articles, and inflection speech etc. the letter systematic, this language system can play a role for expressing as the philosophic language which manages with the complicated problems of the human being.
